The new car smell is actually chemicals in the materials used. Maybe Hans is having a reaction to the chemicals?

That is very possible! I just wonder what I could do about it?? I know the "new car smell" eventually wears off, but I think this poor dog may have a heart attack before then.

Hans is really not afraid of much of anything. Loud noises do not bother him. He just sniffed the end of a loud cordless drill my husband was using the other day. Did not bother him a bit-no pun intended! I even stepped back from it. So...it makes sense to me that if he isn't scared of the new truck, then maybe he is extra sensitive to the chemicals.
